Bats & humming birds belong to___________?
Correct answer: C. Heterotherms
- A. Endotherms
- B. Ectotherms
- C. Heterotherms
- D. Homeotherms
Explanation
Bats and hummingbirds are heterotherms because their body temperature and metabolic rate can vary, especially during torpor or periods of inactivity, rather than remaining constant at all times. They are endothermic in heat production, but choosing endotherms overlooks the more specific classification based on variable body temperature.

About Thermoregulation
Thermoregulation maintains body temperature through negative feedback controlled mainly by the hypothalamus. It covers vasodilation and vasoconstriction, sweating, shivering, changes in metabolic heat production and behavioural responses, while distinguishing heat loss by radiation, conduction, convection and evaporation from temperature regulation itself.
